Yes, Death Watch Bunker, rare drop from Ghosts and Wraiths. Unlimited uses and I believe you can do manufacture schematics from it. Master Chef to learn, bu tonce learned any trader can do it after a respec, without the Food Experimentation points of course.

Yesterday I uploaded screenshots and schematic info for most of the single use Engineering schematics to swgwikia.

I noticed two naming discrepancies with SWGCraft...

A Droid Head
'A Droid Head' is how it is listed in trader draft schematics tab and on bazaar terminals. It is listed as 'Droid Head' on SWGCraft. Personally, I dislike the use of indefinite articles ('A' and 'An') in titles because it adds unecessary confusion.

Cabinet (elegant)
'Cabinet' is how it is listed in trader draft schematics tab and on bazaar terminals. It is listed as 'Elegant Cabinet' on SWGCraft. Since all the crafted container cabinets are named 'Cabinet', to keep them all under the view schematic 'C' list, the naming convention would need to change to something like 'Cabinet (elegant)' for disambiguation.

Here are links (including screenshots) to the other single use Engineering schematics that SWGCraft is missing...

What I settled on was how it is listed in the trader's draft schematic list after it is 'learned'. Because that's what you'll most likely look for in your 'tool' list when you go to craft it and it's also what the crafted item default names to.

Sobuno, is it so that the "Master" levels each profession class is missing? Or do I still need more coffee?
